High Speed Data Acquisition, Wireless IF Digitising, 65MSPS ADC & DAC Board- RF

Overview
The two input channels on the RF employ Analog Devices AD9226 A/D converters (ADC) with 12-bit resolution at up to 65 MHz for high speed data acquisition.

The input signal processing chain consists of 50 Ohm input termination, a high speed low distortion input amp, an optional programmable gain amp giving a signal amplification range of -14 dB to +34 dB, followed by a 7th order low-pass filter to the A/D (ADC).

The twos complement data from the A/D converters (ADC) clock into 1 KWord FIFOs, which are configured to interrupt the host card at programmable levels. Clocking is provided to the two A/Ds (ADC) using either the on-board dual channel DDS or an external clock source.

The two analog outputs commission Analog Devices AD9765 12-bit, D/A converters (DAC). Each channel includes a 7th order low-pass filter, an output buffer amp and has a single-ended output matched to 50 Ohms.

The DACs are directly fed by a 1 KWord FIFO and triggered by the onboard DDS or an external clock source. The DAC FIFO levels are monitored in a FIFO status register and can trigger interrupts to the host card.

The RF module is ideal for: High Speed Data Acquisition, Wireless IF Digitising,  Transient Capture, Noise Cancellation, Vibration Monitoring, Inspection, Ultrasound, Magnetic Bearing Control, Instrumentation, Scanning Probe, Microscopes, Data Acquisition and Logging, Digital Radio.

The RF module can be used for general purpose data acquisition tasks on a PC (fitted to a ChicoPlus or cChicoPlus) or remote from a PC (fitted to a SBC6713e with EtherNet) by using Real Time System Editor.

There is a version of this board with a bigger FPGA fitted so that the user can make use of the extra logic gates.
